Notes: Stream SB is a short perennial channel that is primarily fed by a stormwater outlet from the adjacent residential areas. The stream is incised and downcut, especially in the pools, allowing the hydrology to be influenced by groundwater as well. Stream SB flows west into Booker Creek, within the study area.

Notes: Stream SC is a strong intermittent reach that originates at a large headcut inside the study area and runs west, offsite. It is primarily comprised of pooled water and the banks of the stream are heavily eroded, creating vertical banks. BKFW: 7' BKFD: 2' WW: 3' W D: 1' Substrate: sand,gray. Clarity: clear Flow: pooled
